问题描述
目前,我使用 BaseController 的 onDispatch 方法设置了几个要由应用程序的整体 layout.phtml 使用的变量,我的所有其他控制器都扩展了该方法:
At present I set a couple of variables to be used by the app's overall layout.phtml, using the onDispatch method of a BaseController, which all my other controllers extend:
public function onDispatch(MvcEvent $e)
{
$config = $this->getServiceLocator()->get('config');
$this->layout()->setVariable('platformName', $config['platform']['name']);
$this->layout()->setVariable('platformYear', $config['platform']['year']);
}
这很好用,直到我测试了一些错误页面并发现这些页面没有提供变量,因为它没有使用基本控制器.
This works fine, until I test some error pages and find that these pages do not get provided with the variables, as it's not using the base controller.
如何解决这个问题并为错误页面提供相同的变量?
How can I get around this problem and provide the error pages with the same variables?
推荐答案
更改您正在侦听的事件.
Change the event you're listening for.
在这种情况下,我会将这个逻辑移到应用程序引导事件或应用程序渲染事件(我没有测试过,但它可能会正常工作).
In this case, I'd move this logic to the application bootstrap event or the application render event (I haven't tested this, but it would probably work fine).
一个例子,在你的 Module.php 中
One example, in your Module.php
public function onBootstrap($e)
{
$config = $e->getApplication()->getServiceManager()->get('config');
//$e->getViewModel()->setVariable();
}
尚未测试该注释掉的行,但它应该能让您朝着正确的方向前进.
Haven't tested that commented out line, but it should get you headed in the right direction.
找到使用渲染事件的示例
Found an example of using the render event
public function onBootstrap($e)
{
$event = $e->getApplication()->getEventManager();
$event->attach('render', function($e) {
$config = $e->getApplication()->getServiceManager()->get('config');
$e->getViewModel()->setVariable('test', 'test');
});
}
